No, not even close. See the diagram below.

Copying from Brushy Mountain's 1999 catalog,
below is a ASCII-art top view of what they
call a "Rabbeted Hive Body Joint" (not to
scale, but close).  Don't blame me for the
terminology.  As I said, terminology varies.
Massively, it seems.

The nice thing about it is that friction alone
holds the super together while you nail, screw,
glue, whatever.  As I said, the drawback is that
even slightly non-planar stock will make this
design very difficult to assemble at all.
